Surveillance to identify the exact extent of the number of undiagnosed people living with HIV remains insufficient across Europe. Different estimation approaches exist, using different sources of data, and many countries do not appear to produce any estimates.

Objectives

A project group led by Andrew Phillips, UCL has worked to create a guidance document for countries on data requirements and available methods for estimation of the number of people with HIV. The document outlines all availabl approaches and provides the necessary guidance for using them. It is a first step towards a coordinated European approach.
